Hi,

Can you explain what do you mean by reset ? Do you want to default it to 0 ?
Then just access the Rectangle using its id and set X and Y to 0.

i mean :in listmodel ,every element save a group x and y coordinate.

when program first running,Rectangle :get(0).listmodel.x y:get(0).listmodel.y.
then i press button , so Rectangle :get(1).listmodel.x y:get(1).listmodel.y.,acquire new x and y coordinate.

Well then you can use the "contentItem":http://qt-project.org/doc/qt-5.0/qtquick/qml-qtquick2-flickable.html#contentItem-prop and get the childrens and then access its x and y.

E.g

@
listview.contentItem.children[1].x
listview.contentItem.children[1].y
@

This gives the item a index 1 in ListView.
